I was looking at drop-in trigger groups today and came across a CMC single stage that felt good and wasn’t quite as expensive as a lot of the others.

On the package it noted “small pins”. Which I believe was something 0.154 or something.

What sized pins are compatible with the M-22?

Do I need to looking for groups with the small pins or large pins,,, or does it matter for installation?

You want small pin. The only company that made large pin lowers was Colt back in the 90's during the ban.
